It's not just cloud SaaS apps, it's everything that is based on unbounded transactions. Every subscription-model service, every Uber-like service, every social media site, every "free" email provider, everything. If you have to pay more than once for the same thing you're at risk.
It's certainly true that some providers are worse than others, but I don't think any of them are "safe" in the long term. Self-hosting is one solution, but even apart from that, a competitive market of multiple providers makes rugpulls like this less likely, because in such an environment even people who are not directly screwed may decide to jump ship to avoid being screwed later.
